Ok the alarm has just gone off again at work following the 'ignition trick' this morning. So we've had approx. four hours of no alarm, then it went off again. It seems to run for a few minutes, then stops, then starts again and sounds for 1 minute or so maybe longer, then stops briefly, then starts again.... I cannot lock the car and leave it locked without the sodding alarm activating...FFS. When I deactivated it with the key fob it beeped three times again, I don't know whether this is significant?
